RESUMO

Salmeterol is a long acting, highly selective, beta2-adrenergic agonist. It prevents asthma symptoms in patients with mild or moderate disease and improves nocturnal asthma and sleep quality. We evaluated the bronchodilator and bronchoprotective effect and duration of action of inhaled salmeterol in patients wlth asthma. We compared the bronchodilator and bronchoprotective effects of salmeterol with salbutamol in 34 patients with asthma. Diagnosis of asthma was confirmed with methacholine challenge test or airway reversibility test. We performed the symptom index questionnaire, peak expiratory flow rate, pulmonary function test and methacholine challenge test. Symptom scores were more improved with salmeterol treatment than salbutamol treatment. After salmeterol inhalation, mean FEV1 increased from 1.95L(pre-treatment) to 2.04L(early stage in the treatment), 2.06L(late stage), 2.03L(follow up). There was no difference in FEV1 between early stage and late stage after salmeterol treatment. With salmeterol, there was a significant increases in PC30 on methacholine challenge test ( PC20 4.96 : 16.42). Salmeterol is a potent, long-acting bronchodilator, with a slower onset and longer duration of bronchodilation than salbutamol. It also has bronchoprotective effect and shows low incidence of adverse effects.

RESUMO

Carcinoma of lung is classified by histologic cell type, this is based on predominant major cell population by tissue specimen. But in fact a range of 13% to 63% of lung cancer has been appeared to be heterogeneous cell type at the light microscopic level. After treatment of the mixed lung cancer and/or with time there are reports that cell type is changed. Because it is possible that the tumor were pleomorphic and that the antitumor therapy eliminated the more sensitive cell population and permitted the subsequent emergence of the more resistant cell population. The authors reported here, a case of 32 year old female patient with mixed lung cancer composed of three cell type, and this is the first case in Korea.
